“…It is also observed from the graphs that the shear strength of double lapped joint specimens (epoxy, vinyl ester and polyester) is almost same as single lapped joint but more load to required to break the specimen is needed [17]. This is due to thickness of double adhesive joints of specimens, as the specimens having double lapped joint in order to have 0.2 mm thickness and less shear strength, whereas the specimens having single lap joint in order have 0.1 mm thickness shown in Fig.…”

The objective of research work is to establish the influence of environmental factors such as moisture and temperature on the shear properties of metal and polymer joints. The specimens of metal and polymer joints were prepared with aluminium plate and glass fibre reinforced plastics. Here three types of resins were used for joining the metal and polymer composites viz. epoxy vinyl ester and polyester. The joint specimens were exposed to 80 C temperature and relative humidity of 90% for 25 days in environmental chamber. The single and double shear strength of the joints for ascast and hygrothermal exposed specimens are investigated. The results showed that the strength of hydrothermal specimens decreased about 25%, 18% and 33% for epoxy, vinyl ester and polymer adhesive joints respectively. The result also shows that vinyl ester joints exhibit lower water absorption and property degradation of the joints.

“…The most generally used fabricating technique in the marine and aircraft industry is hand lay-up, which is simply Includes setting the prefabricate at the pattern and sooner or later making use of resin either through brush or roller.. The main advantages are low cost apparatus and extensive mixture of products and the Disadvantages are time overwhelming undesirable and circumstance intended for works in view of the unsafe gases to resins discharge, easy to create air bubbles [16].…”

“…This method is preferred since it has superior mechanical strength and low void content. Even though prepreg contains the best properties, it has some drawbacks such as high price, short shelf life and circumstances that need convenient temperature and humidity [16]. Also, this method is a tedious one to fabricate complex shapes and structures.…”

Materials having low density combined with superior strength are gaining demand in the field of automobiles, aeronautical and military appliances. Fiber Metal Laminates (FML) is becoming the material of choice for the above mentioned applications because of the ability to tailor it to meet the demands of the end applications. This paper throws light on the commercially available for of FMLs, its production methods, property enhancement and diverse applications. As such Carbon fibre reinforced composite are preferred for making automobile bonnets and fuselage in military aircraft due to the superior strength to weight ratio. On the other hand glass fiber reinforced composite materials are used to manufacture railway locomotive body panels due to the high tensile strength and impact strength. This paper can be used as reference for budding engineers who want to gain first-hand knowledge on FMLs.

“…. Based on their results, the authors in suggest that the polymer matrix is sensitive to electrochemical degradation and the carbon fiber remains with very little loss of mass even at very high current densities (up to 3 A/m 2 of anode surface). However, studies of the microstructure at the paste–anode interface are scare.…”

Impressed current cathodic protection (ICCP) is a powerful method to prevent and stop corrosion of steel in concrete structures. To evaluate the long‐term effect of ICCP, accelerated tests have been adopted using high current densities. A carbon fiber reinforced polymer mesh was introduced as anode. The presented research focused on the changes at the paste–anode interface as a consequence of applying current. The treated samples were characterized by various techniques. Calcium dissolution was found with an average thickness of 0.34 mm around the anode after charges of 6 × 106 C/m2 were applied, equivalent to applying 4 mA/m2 of anode surface for 30 years. Calcium dissolution resulted in a white zone around the anode, where the calcium silica ratio was lowered and almost no crystal phase was observed. NMR results show clear Q3 and Q4 peaks in the white zone, which contained extended branched and networked structures of hardened cement paste. An increased resistance caused by the formation of the white zone may eventually make the system fail because of insufficient current densities. CFRP has been proven suitable for ICCP application even at a current density of 4 A/m2 of anode surface.
